    Abstract: Apparatus for creating a controlled pattern of ablation throughout the interior of an organ or body cavity while minimizing thermal damage to collateral tissue includes a microporous balloon mounted on a catheter. The balloon, bearing electrodes embedded in the surface, is inserted into the target body region and inflated, whereupon the electrodes come into contact with the interior of the targeted organ. Because of its microporous nature, fluids for cooling or various therapeutic purposes may pass through the surface of the balloon to the target site. Sensors monitor conditions such as temperature and impedance at the site, providing required feedback for delivery of RF energy for ablation, and administration of cooling and hydrating fluids. A second balloon or other means isolates the treatment area and controls the flow and accumulation of body fluids and treatment fluids minimizing adverse treatment effects from fluid accumulations, and anchoring the catheter in place.

    Abstract: A method and apparatus for treatment for body structures, especially internal body structures involving disorders involving unwanted features or other disorders, that does not require relatively invasive surgery, and is not subject to other drawbacks noted with regard to the known art. A relatively minimally invasive catheter is inserted into the body, treatment of the body structures is applied using the catheter, and the unwanted features or disorders are relatively cured using the applied treatments. The applied treatments can include application of energy or substances, including application of energy (such as of radio frequency energy, microwave energy, or laser or other electromagnetic energy) or substances (such as collagen or other bulking, plumping, or shaping agents; saline or other energy-receiving electrolytes; astringents or other debulking, reducing, or shaping agents; antibiotics or other bioactive, chemoactive, or radioactive compounds). More than one applied treatment can be performed, either in conjunction, in parallel, or seriatim, so as to achieve a combined effect more substantial than any one individual such applied treatment.
